Some facts here might be nice, to clear up the guesses and speculations in this thread:

"We are excited about our plans to bring Skype to smartphones running the brand new BlackBerry 10 platform," said Bob Rosin, VP & GM of Business Development for Microsoft's Skype division. "We are working closely with BlackBerry to ensure Skype runs great on BlackBerry 10 devices. This will give BlackBerry 10 users a great Skype experience, including free voice and video calling, sending instant messages and text messages, sharing photos, videos and files, and calling to landlines and mobiles at Skype's low rates."

A lot of the BB10 launch was super hype prior to launch. I am not sure anyone else noticed, but at one point they were demonstrating screen sharing between a phone in London and one in New York. The phone in London was flipping through their pictures, which would show up on the phone in New York. I pointed out to the people in my office, that the last 5 pictures in that slide show showed up on the phone in New York, before the phone in London flipped to them. The last one by a good 3 seconds. This tells me that it was a pre-prepared sequence that was being shown (and subsequently lost sync), not a live demonstration of their software, as they claimed.

I am pretty sure it was because of the two different connections: the one was directly through the phone (BBM) and was faster than the streaming connection line on the presentation screen...This kind of "async-behaviour" is pretty normal for streaming... Besides: if RIM (Blackberry) would lie about the streaming-quality during their presentation it would mean that the OS is not ready yet... if that was the case I am pretty sure they would not show that feature... I mean the phones are coming during the next couple days... they would never risk such a huge disaster just because of the presentation's sake...

Sounds like a lot of hot steam. Android and iOS have Skype too, why shouldn't BB10 get it? And so what if the one on this platform is "in beta" - it is still a working app that you can download. Sure, it has limitations and bugs but so do the apps on the other platforms. Actually, I don't think I've encountered any piece of software from Skype (except the desktop client) that is really all that well built.

Not to mention how Skype is better integrated with WP (despite it being in "beta") than any other OS.

Skype is meant to be a multi-platform messaging client - that's one of its major strengths. What's the point of limiting that just so you can go around showing people that "your phone does it better"?

Obviously, this is totally different from the game issues where Microsoft deserves a lot of criticism for not leveraging every opportunity to highlight their OS.

i bet their skype app would be even more unstable than ours. common, microsoft still has their senses they must support their platform first. i hope.
it's been 3 months since skype preview released. losint hope

I actually run the Canadian operations for a large Live Streaming CDN. I am familiar with sync issues. I am also familiar with the fact that sequences such as this are frequently filmed in advance (which is why you can't actually see their hands behind the podium while they are "presenting") to eliminate the risk of connection glitches. It is similar to a musician using a "backing track" and lip synching to eliminate potential for a voice crack, etc.

Having looked at the presentation a second time, I can tell you with a fair bit of certainty that the person on the controlling phone was not making the same sequence of gestures as the receiving phone displayed (the controller phone appeared to be "hunting" for the appropriate image and was moving between photos in both directions, that was not reflected on the receiving phone, regardless of synch timing).

Microsoft needs to make some strong changes on WP8, add some basics functions that all the other platforms had, including the dead Symbiam, improve the best functions on WP8 and make something new, to make the costumers want his phone... Because the new Windows phone 8 is becoming old, against all the other TOP 3 OSs ... Microsoft, C'mon ... Let us happy, not worried with your product, our OS.
